Robust Protocol for the Synthesis of BSA Nanohydrogels by Inverse Nanoemulsion for Drug Delivery

In a highly efficient and reproducible process, bovine serum albumin (BSA) nanogels are prepared from inverse nanoemulsions. The concept of independent nanoreactors of the individual droplets in the nanoemulsions allows high protein concentrations of up to 0.6% in the inverse total system. The BSA g...

Zusammenfassung:In a highly efficient and reproducible process, bovine serum albumin (BSA) nanogels are prepared from inverse nanoemulsions. The concept of independent nanoreactors of the individual droplets in the nanoemulsions allows high protein concentrations of up to 0.6% in the inverse total system. The BSA gel networks are generated by the 1-ethyl-3-[3-dimethylaminopropyl]carbodiimide hydrochloride coupling strategy widely used in protein chemistry. In a robust work-up protocol, the hydrophobic continuous phase of the inverse emulsion is stepwise replaced by water without compromising the colloidal stability and non-toxicity of the nanogel particles. Further, the simple process allows the loading of the nanogels with various cargos like a dye (Dy-495), a drug (ibuprofen), another protein [FMN-binding fluorescent protein (EcFbFP)], and oligonucleotides [plasmid DNA for enhanced GFP expression in mammalian cells (pEGFP c3) and a synthetic anti-Pseudomonas aeruginosa aptamer library]. These charged nanoobjects work efficiently as carriers for staining and transfection of cells. This is exemplarily shown for a phalloidin dye and a plasmid DNA as cargo with adenocarcinomic human alveolar basal epithelial cells (A549), a cell revertant of the SV-40 cancer rat cell line SV-52 (Rev2), and human breast carcinoma cells (MDA-MB-231), respectively
